| Asian | Caucasian | African |
Density of Follicular Unit per sq. cm/ sq. inch/ sq. m. m. | 60- 80 per sq. cm or 375 -500 per sq. inch or 0.8 per Sq. m. m. | 100 per sq. cm or 625 per sq. inch or 1.1 per Sq. m. m. | 60 per sq. cm or 375 per sq. inch or 0.65 per Sq. m. m. |
Hair per per sq. cm/ sq. inch/sq. m. m. | 120 – 160 per sq. cm or 750 -1000 per sq. inch or 1.6 per Sq. m. m. | 200 per sq. cm or 1250 per sq. inch or 2.2 per Sq. m. m. | 120 per sq. cm or 750 per sq. inch or 1.3 per Sq. m. m. |
Total hair in scalp | 80000 | 100000 | 60000 |
Total Donor graft available | Medium due to medium density and smaller size of donor | Maximum due to higher density and larger size of donor (> 35 cm x 7.5 cm = 262 cm2) | low due to low density and smaller size of donor |
Donor hair character | More thickness | Average thickness but usually skin hair contrast is less esp. with blonds and light hairs | More 3 or 4 hair follicular units and curly hairs |
In the head of an average male with a hair bearing area of approximately 80 square inch area,
The more the density, the more is the movable hair the number of square inches of scalp that can be moved depends upon the looseness of the scalp (something we call Scalp Laxity). The more square inches we can safely move, the more hair we can transplant
With good decision making by the doctor, large sessions should not scar more than multiple smaller sessions but there may be a cost for aggressive decisions in large session transplantation if the doctor is not experienced in such procedures. So there is a balance between what can be done and what should be done. The real issue here is not if it can be done, but whether or not they will actually grow. Various factors affect the overall outcome of the transplant are
1. Density of the hair: A doctor can transplant as high as 50% of the original density but hair transplant is not an Olympic contest of how may grafts one can place in a sq. cm. But it is certainly an issue where you have to see that how many grafts really grow. It is important to focus more in the issues of coverage and fullness. Some studies have shown that by crowding the grafts more than 40 per square cm, blood supply may be compromised & the successful growth of these grafts starts to fall off significantly. If there is hair already present in the transplanted recipient area, there is great likelihood that it would damage the existing hair as well as obtaining poor growth. Well the area of grafting is important; the hairline needs higher visual density than the area behind it for cosmetic reasons.
2. Donor Laxity: Tight scalp restricts the harvestable number of grafts in a megasession because the width of the strip that can be removed becomes restricted.
3. Donor Area size: Assuming normal density of hair, a person with the Norwood Class 7 hair loss pattern (the worst case) will lose 70% of the total hair he was born with. This will leave him with a 3 inch by 14 inch wreath of hair around the back and sides of his head. This area is less in the Asian head due to smaller size of the head both in the hight and the length.
4. Donor Scarring: More the number of surgeries done more is the donor scarring and more is the possible loss in the scarring and therefore less is the available grafts. Therefore megasessions can harvest more number of total grafts than multiple smaller sessions which lead to multiple scars.
5. Hair shaft thickness. The coarser the hair, the better it supplies bulk. Hair bulk is a critical element in producing fullness and coverage. Coarse hair is better than fine and wavy is better than straight in giving the volume or coverage. For the same coverage given by 1000 hairs of 80 micron diameter one needs 1300 hairs of 0.7 micron and 1800 hairs of 0.6 micron and 2560 hairs of 0.5 micron diameter. A blonde with white skin, may only have to return 15% of the hair density, with coarse dark hair , you might get away with 25% of your original density, and if your hair is wavy with good thichness it may be even less. On the other hand Fair skin with thin black hair may require more number of grafts to be transferred to achieve the reasonable coverage. Oriental hair with good shaft thickness has better coverage capacity compared to thin Caucasian hairs.
6. Pre existing DUPA: For an African or Asian man under 25, a donor density of 120 per sq.cm. without “DUPA-Diffuse Un Patterned Alopecia” may make a good candidate with high quality hair, while a Caucasian with he same density having DUPA might make a very bad candidate for a hair transplant for many reasons..
7. The size of the balding area. The more bald you are, the more hair you might need. Sometimes, the goals has to be more realistic due to limited supply or a demand that is too high. One with the impaired vision aims for the best possible improvement in vision by the treatment but one with the loss of both eyes should aim of a helpful stick or a faithful leading dog. Stage 7 may have bald area of 250 sq.cm or more to give coverage to that area with average density of 30 would need 250 x 30 = 7500 grafts which need at least 2 sessions to give coverage.
8. The characteristics of your hair. African hair due to its curliness has a better coverage and volume giving capacity. The Italians and French had the best wavy hair. Straight is the most challenging, as found in many Asians.
9. Color/contrast between hair and skin color. This is critically important. A Class 6 pattern blonde person could reduce his hair population to 85% of its original density and still look full as the blonde hair and blonde skin have low contrast. The same applies to black hair and black skin, brown hair and brown hair, sandy hair and sandy skin and any skin color with white hair. Salt and pepper hair works very well. It difficult to achieve good result in people with white skin with black hair.
10. Length of the hair: Longer the hair the better the coverage and fullness. I normally advise the transplant candidate to keep transplanted hair long and not very short.
11. Elasticity of Recipient: Scarred or callous scalp tissue: The health of the scalp determines just how close you can place the grafts (for scalp that is atrophic and lost its infrastructure of blood vessels, glandular structures and fat; less density is often better). The reasonable upper limit of density numbers from a transplant perspective is up to100 - 120 hairs per square cm. This type of density, however, requires supple skin that still has elastic properties. Scars do not have this characteristic. Also scars have an abnormal blood supply when compared with normal skin. Much of the infrastructure and microcirculation in the vasculature is not present in scar, so transplanting very high densities may not produce good growth.
12. Skill and Ability of the surgeon and team: to transfer this number safely the size of the instruments for making sites, the skill of the surgical team at placing grafts tightly together
13. Other Characters; emerging angle, oiliness, sheen, static electricity etc.
Dear friend this is a very useful question for all those who want to undergo HT to be answered. I give you a calendar of recovery and for resuming various activities: The following table is the general guideline for the anticipated course for the average patient undergoing Hair Transplantation.
Time after HT | Progress & Recovery | Activity possible or required |
Day 1 Immediately after surgery | Heavy headedness, mild headache or rarely momentary giddiness. Need some pain killer. Grafted site may ooze some blood. | Grafted and the donor site needs to be washed gently after 4 to 5 hours with baby shampoo and spray of clean water. Can comb the hair carefully with the wide toothed comb. A short walk, watching TV etc. Go to the sun with a cap on for 2-3 months Eat every thing that you like. Sleep on the back; avoid sleeping on sides or on tummy. Sit at 45 degree angle with the back and the head bent backwards. Avoid “yes” & “No” neck movements of neck. No Tobacco; smoking (healing and hair growth problems) or alcohol. Avoid hand kerchief or Bandana on the recipient. Passive sex (masturbation) is ok |
Day 2 | Some soreness, tightness and numbness. Need some pain killers | Hair Oil can be used ( may even help to soften the scabs) Can use ice packs for 2-3 days on forehead to avoid swelling |
Day 3-4 | Soreness begins to disappear. Occasional pain killers needed. Some numbness may continue Scabbing is largely gone if properly washed. Moderate redness may be present. Some swelling may appear on forehead. Hair transplant grafts should have firmly set in and humidity/sweating should not affect them | Active Sex is Ok now |
1 week | Soreness is generally gone. Occasionally some numbness persists. Redness is minimal to absent. Swelling is usually gone. Scabs start separating& the hair may also fall along with the scab but the graft is taken by the body. | Can start full aerobic exercise ( walk, run, yoga etc but no sit ups, pull ups or weight lifting) |
10-12 days | Grafts are now well incorporated in the body and it is ok to remove the scabs by rubbing during the bath | |
2 weeks | Looks and feels like a 4-day-old beard. Sutures begin to absorb. Discomfort is gone. | Hair cut, colour, style, use of relaxer or bleaching etc is possible provided the wounds are healed and the scabs are gone. Sports can be started. Concealers like Toppik can be used and Non comedogenic Sun screen lotion can be used to protect scalp Scalp massage is possible now |
1 month | Transplanted hair is shed as the follicles enter a dormant phase. Knots at the ends of the absorbable sutures fall off. | Can start weight lifting, pull ups, or sit ups. Sun bathing, |
3-6 Months | Transplanted hair begins to grow first as very fine hair. Any residual numbness in the donor area is generally gone. | Scalp exercise to facilitate the 2nd Hair Transplant session can be started now. |
8 months | Transplanted hair becomes combable or groomable but transplant appears thin as hair continues to grow and thicken. Slight textural change in hair is occasionally present. | It may be possible now to go for 2nd session of transplant now |
1 year | expect over 95% of the grafts to have grown | |
1-2 year | There may be additional fullness during the second year. Any textural change in hair usually returns to normal | |
Usual Time of Recovery and Resuming of activities:
Pain, discomfort or tightness in the donor area: 2-5 days
Swelling: Immediate swelling of anaesthesia disappears after few hours but the post operative swelling although less common these days may appear after 24 hours and usually disappears in 3-5 days
Numbness: the head lasts because of anaesthesia for few more hours after surgery but numbness above the stitches may last from 1-12 months.
Scabs: by regular cleaning usually gets cleared by 3-7 days if it is there it can be removed by rubbing during bath after 12 days
Sun Exposure of scalp is avoided for 2-3 months by use of cap/ cover or Sun block
Passive sex is possible even from day 1 and active sex after 2-3 day is Ok
Avoid smoking for 3-6 months
Walking is ok from day one
Aerobic exercise (walk, run, yoga etc but no sit ups, pull ups or weight lifting) after 1 week
Weight lifting after 1 month
Hair cut, colour, style, use of relaxer or bleaching etc is possible after 2 weeks provided the wounds are healed and the scabs are gone
Grafted hairs will fall some along with the scabs and the rest by 1 to 2 months
New hairs start growing by 3-6 months and Transplanted hair becomes combable or groomable but transplant appears thin as hair continues to grow and thicken. Slight textural change in hair is occasionally present. There may be additional fullness during the second year. Any textural change in hair usually returns to normal
1. Goals accomplished quickly
2. Fewer traumas and damage to donor hair and less donor scars considering multiple scars of smaller sessions
3. More graft harvest than multiple small sessions. Smalller sessions have higher likely damage to the donor follicles while strip removal and also dut to scarring
4. Comparatively less expensive for patient in terms of travel, surgical and off the work time.
A: Easily avoidable by a good doctor and patient:

Well this product based on Aminexil has a credibility due to backing of company like L’Oreal. But the product is not tested according to FDA standard so no body can say that which one is better. But it is supposed to be working in the similar way as Minoxidil by increasing the the period of Hair Cycle. As for the safety also minimal data of credibility is available about Aminexil. Minoxidil is a FDA approved medication for prevention Hair Loss and has been well studied and its effects are well documented.
Hair weaving is a method of fixing (anchoring) the wig to your own hair. They weave your own hair in a “U” shape and with the thread the wig is tied to your own hair. This is a temporary method with lot of maintenance. It is in the long run, more expensive than the other options like hair transplant. And the expenses don't stop there. First, you will always need two hairpieces -- one that you wear and one that is being re-styled. Soon (usually in about a year to 18 months), you will need to replace both. Although human hair is used, it is constantly being dyed, brushed and permed to match your hair. After a while, just like your own hair, each hair strand breaks or becomes over-processed and the material it is attached to starts breaking down from the constant reattachment. You will also have to visit the hair centre every four to six weeks to have your hair trimmed and have the piece reattached and blended. Sweating and local hygiene is at stake and the constant burden of wig is also cumbersome. Stress on your existing hair, can cause permanent damage to your remaining hair.
A wig is a non-surgical hair addition by external hair-bearing device or cap added to existing hair or scalp to give the appearance of a fuller head of hair. Wig is known by various names like hair weaves, hair extensions, hairpieces, toupees, Hair Integration, non-surgical hair replacements and partial hair prostheses. Devices may consist of human hair, synthetic fiber or a combination of both. The device may have various bases a textile net in which hair weft can be tied or specialized polymer silicone
in which hairs fibers can be injected etc. It may be ready made or custom made.
It can be hand tied or machine made. Custom-fitted, hand-tied, human-hair wig are the best but most expensive.
EXISTING HAIR: Weaves (use thread)fusion (Use clips)
bonding (use double sided tape or adhesive liquids),
cabling, micro links, beading are general terms of techniques all attached to the client’s existing hair. All these techniques use the existing hair structure.
TO THE SKIN: Includes adhesives such as two-sided tapes and new improved waterproof liquids. Vacuum bases- held on by suction through an air tight fitting foundation.
All are used to provide more security for the active lifestyle, and they are all dependent on the growing existing hair and therefore must be reattached or tightened as the existing hair grows. (Techniques that stress your existing hair, such as weaves, can cause permanent damage if done incorrectly or on an inappropriate candidate. Even temporary clips attached too tightly can cause permanent hair loss.)
Diffuse Unpatterned Alopecia (DUPA) is a condition where the hair has miniaturization (over 30%) throughout the scalp without a particular pattern to it. It is a relatively stable condition that may appear at any age. Senile alopecia in old age has similar features. DUPA in women with pattern hair loss is relatively common esp. in post menopausal cases. DUPA is believed to be, genetic and hormonal. In 50 % case it responds to Finasteride 1mg by 12 months; in slowing down its progress and in about half of male patients it get better by reversal with Finasteride. Half of patients have no effect of the medications. Using minoxidil would require a massive application to the entire scalp, it is worth trying. I also prescribe some nutrients like vitamins, minerals and amino acids. Cosmetic products like Dermmatch or Toppik alone or in combination are very useful for both DUPA and DPA and they are safe to use for regular use. The significance of this condition is that Hair Transplant in this condition may not be very satisfactory and therefore are often refused.
There is another condition called Diffuse Patterned Alopecia (DPA) is an androgenetic alopecia characterized by diffuse thinning in the front, top, and vertex of the scalp in conjunction with a stable permanent zone in male ( one can compare it with female pattern hair loss). Usual pattern loss in male is by beginning of loss in frontal or crown area and but in DPA the hair loss starts in the front, mid scalp and crown altogether. Diffuse Patterned Alopecia is usually associated with the persistence of the frontal hairline the hairline of the
